As Ian says I wouldn't bother trying to wrap any bicycle parts possibly the only part you may get away with is the bars but ii all honesty I think they'd look shite to put it bluntly.
Looking at the picture I'd say that the most faded part is the chainset. The only gold alternative I can find at a reasonable price is this Sturmey Archer http://www.ebay.co.uk/itm/STURMEY-ARCHE ... 4cfe2c7d73
but it is only single speed. You could use spacers and mount two rings on there I'm sure but I wouldn't.
I'd be tempted to change it to a black chainset (as the newer Record Spint had) but add Gold chainring bolts and maybe a gold inner ring (black outer) to keep the bling. eBay revealed these http://www.ebay.co.uk/itm/MOWA-Double-A ... 3a75449ca5
which would look fantastic imo, but a little dear!
I did have a very similar bike just had a different paint job, I can't recall the name, and I remember the chainrings were steel which added quite a bit of weight to the bike.
